What is Round Robin DNS?

Round Robin DNS is a creative way to relieve the server width requirements and web hosting zone using a series of IP addresses. This technique is particularly useful for companies whose websites gain a very large number of hits and/or a large number of bandwidth. Think about these IP addresses like A, B, C and D. When the first user approaches the web, this type of DNS system brings the user to address A. The second user becomes to B, etc. Once used A, it goes to the back of the line; The fifth user approaches address a. Despite the sequential nature of the example, IP addresses are not assigned in the sequence order. Rather, they are assigned in a random order. Like the Robin Sports round tournament, in which one team plays each other team, Round Robin DNS, if allowed, will assign one user every available IP address. Of course, this will not happen every time, but it is conceivable.

Of course, users see none of this. Every single user who approaches the company's website sees exactly what he is to see. The vast majority of websites show the domain name that are letters, not numbers. With a round DNS Robin, however, one particular IP address may not receive any intervention. This type of system is commonly used by companies that have multiple versions of the same website that live on different servers, but individual website owners also use a protocol for the same reason.
